Possible IB

anna
I'41 TTC #1 for 2yrs. My cycles are 25-27 (ovulating normally on CD11) but on CD19 had light dark brown-red CM for 2 days. Today I am either CD25 and 14dpo for AF to show up, or CD7 if IB was really a week early period. I'm hot for days, sleepy and tired, BFN, headaches...all but this time PMS soreness of breasts is absent. Anyone had IB and your experiences?
